title: Effectiveness analysis on the physical activity and the health benefit of a community population based program.
abstract: OBJECTIVE
  To evaluate the community-based health promotion effect of physical activity.
  
  
  METHODS
  The residents aged 18 and above from two communities in Gongshu District of Hangzhou City, Zhejiang province, were randomly selected and recruited for the multi-strategy and comprehensive physical activity intervention. Questionnaire survey, physical check up and blood biochemistry were conducted.
  
  
  RESULTS
  After this two-year intervention, the time of the participant spent on weekly physical activity of moderate intensity increased from 464 min to 542 min (P<0.05), with an average increase of 78 min. Time spent in walking every week increased from 533 min to 678 min (P<0.05), with an average increase of 145 min. The body weight, waistline, blood pressure and heart rate all reduced significantly (P<0.05); the vital capacity increased significantly (P<0.05); and the related biochemical indicators were also improved.
  
  
  CONCLUSIONS
  Comprehensive and evidence-based physical activity interventions targeting community population can improve the levels of physical activity, related body measurement and biochemical indicators.
